ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 244,313, dated July 12, 1881.

Application filed May 6,1881. (No model.)

To all whom it may concern:

Be it known that I, J osnPH S. Ronnnrs, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Elevator-Buckets, of which the following is a specification.

My invention consists in an elevator-bucket the greater portion of which is constructed of sheet metal, with aband or hoop of heavier metal forming its working-edges, and formed as hereinafter particularly described.

Referring to, the accompanying drawings, which are made aparthereof, and on which simi-. lar letters of reference indicate similar parts, Figure 1 is a perspective view of an elevator bucket embodying my improvements; Fig. 2, a transverse vertical section thereof on the dotted line 00 w, and Fig. 3 an under-side plan of the same.

In said drawings the portion marked A represents a section of sheet metal, which constitutes the bottom and back side of the bucket; B, a section of which the front side and two ends thereof are principally formed; and G a thicker piece running around and projecting above the top of the piece B, and forming the working-edge of the bucket.

The piece A starts from the lower front edge, runs across the bottom and up the back, formin g said bottom and back, and preferably turns over and runs part way down said back again, forming a double thickness of metal where the bucket is riveted to the belt which carries it.

The piece B forms the greater portion of the front side and two ends of the bucket, and is connected to the piece A at all points where the two come in contact by seams b. This piece is bent so that the corners shall-be square at the bottom of the bucket, but so that those at the top on the front side shall be round. The corners at the bottom are square, on account of the seams being more easily and cheaply made than if they were round, while they are equally as good. Those at the top are as easily made round, while they wear much longer in that form, as they have more wearing-surface. A

bucket having its corners constructed in .this manner has therefore a considerable advantage over one constructed with its corners of a single form, either one or the other, as in an article so extensively in use as this a trifle saved in cost of construction on each one amounts to a large sum on the aggregate number used, and this is in this case combined with the greatest durability, which is even more important.

The pieces A and B are both constructed of thin metal, light sheet iron or tin being preferred.

The piece 0 is preferably of hoop-iron, and is intended to be considerably heavier than either of the others. It passes around the top edge of the part B, and is secured thereto by rivets c. It also preferably passes partly or wholly around behind the back portion, in order that the rivet-holes a may also pass through it as well as the back. It being stronger than the part B, is so attached as to project above the edge of the same and form the workingedge (or the edge which comes in contact with the grain) of the bucket.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As an improved article of manufacture, an elevator-bucket having its bottom and sides constructed of sheet metal, and the top edge of the front side and ends of hoop-iron or like metal, which is riveted to and projects above the thinner material, for the purposes set forth.

2. An elevator-bucket formed of section A, which comprises the bottom and back side, and section B, which comprises the two sides and front of said bucket, the parts being con-. 'nected together by seams b where they come in contact, substantially as shown and described.

3. The combination, in an elevator-bucket, of the three parts, A, B, and O, constructed, arranged, and attached together substantially as shown and described, and for the purposes specified.

In witness whereof I have hereunto set my
